The proximal articular set angle (PASA) is used in the evaluation of hallux abducto valgus, as well as a criterial parameter for the selection or rejection of various hallux abducto valgus corrective procedures. The authors casually observed variability in the measurement of PASA in clinical situations, stimulating the development of the presented study to determine if, in fact, the measurement of PASA varies excessively from one physician to another. The results clearly indicate that the interevaluator measurement of PASA is excessive (p less than 0.001 in seven of eight x-ray series and p less than 0.01 in one of eight x-ray series). The authors discuss the clinical implications of the findings. Furthermore, the shortcomings of the study are discussed, specifically the inability to conclude about intraevaluator variability.
近端关节设定角（PASA）用于拇外翻的评估，也是选择或排除各种拇外翻矫正手术的一个标准参数。作者在临床中偶然观察到PASA测量值存在差异，从而推动了本研究的开展，以确定PASA测量值在不同医生之间是否确实存在过大差异。结果清楚地表明，评估者之间PASA测量值的差异过大（八个X线系列中的七个p值小于0.001，八个X线系列中的一个p值小于0.01）。作者讨论了这些发现的临床意义。此外，还讨论了该研究的不足之处，特别是无法得出评估者内部差异的结论。
